The Little Mermaid by Hans Christian Andersen

Far out in the ocean, where the water is as blue as the prettiest cornflower, and as clear as crystal, it is very, very deep; so deep, indeed, that no cable could fathom it: many church steeples, piled one upon another, would not reach from the ground beneath to the surface of the water above. There dwell the Sea King and his subjects. ~ The Little Mermaid by Hans Christian Andersen
